Ibintu ugomba gusuzuma mugihe upima vicosity ya minisiteri ya minisiteri HPMC

HydroxyPropyl methylcellse (HPMC) ni ngombwa cyane mu mico yumye, kunoza imitungo nko gukorana, kugumana amazi, no kumeneka. Gupima virusi ya HPMC mu miryango ivanze-yumye ni ngombwa mu kubuza ubuziranenge n'imikorere ihamye. Ibyatsi bigira ingaruka zoroshye yo gusaba, gushiraho igihe, n'imbaraga za nyuma za minisiteri.

Ibintu bireba gupima urukwavu
1. Ibigize minisiteri ivanze
Ibigize minisiteri ivanze-byumye birimo sima, gukusanya, inyongeramusaruro nka HPMC, kandi rimwe na rimwe izindi polymers. Umubare w'ibi bigize bigira ingaruka kuri viscosity. Imyitozo yo hejuru ya HPMC muri rusange yongera viscosity kubera imitungo yayo ikabije. Byongeye kandi, ubwoko no gutanga amanota yo gukusanya birashobora guhindura ibiranga umuryango wa minisiteri.

2. KUBONA UBURYO
Uburyo nuburebure bwo kuvanga bigira ingaruka zikomeye kubipimo byayo. Kuvanga bidahagije birashobora kuvamo imvange idahwitse, biganisha ku mbarika idahwitse. Kuvanga bikwiye kwemeza ko HPMC yatatanye byuzuye muri minisiteri, itanga ibisubizo bihamye. Kuvanga umuvuduko, igihe, kandi ubwoko bwibikoresho bigomba gutondekwa kubipimo byizewe.

3. Ikigereranyo cy'amazi
Ikigereranyo cyamazi (w / s igipimo) ni ingenzi muguhitamo virkositimu. Ibirimo byinshi muri rusange muri rusange bigabanya ubuyobe, bigatuma amazi menshi. Ibinyuranye, ibintu byamazi yo hepfo bivamo ibintu byinshi, uruvange rwa virusire. Guhuriza hamwe muri G / S ni ngombwa mugupima urujino yoroha.

4. Ubushyuhe
Ubushyuhe bugira ingaruka kuri viscosiya ibisubizo bya HPMC. Mugihe ubushyuhe bwiyongera, viscosiya za HPMC iragabanuka kubera kugabanuka mumikoranire ya moleka. Kubwibyo, ni ngombwa gukora ibipimo byagaragaye ku bushyuhe bugenzurwa kandi buhoraho kugirango wirinde guhinduka mubisubizo.

5. PH
Urwego rwa PH ruvanze rushobora guhindura viscosity ya HPMC. HPMC yerekana virusi zitandukanye ku nzego zitandukanye za PH, hamwe nindangagaciro zikabije zishobora gutera gutesha agaciro polymer no guhinduranya vinosity. Kugumana aho bidafite aho bibogamiye alkaline ph nibyiza kubisomwa bihamye.

6. Imyaka ya minisiteri
Imyaka cyangwa igihe cyashize nyuma yo kuvanga birashobora kugira ingaruka kuri virkositimu. Inzira ya hpmc irashobora gukomeza igihe cyagenwe, gahoro gahoro gakondo. Ibipimo bigomba gufatwa mugihe gihoraho nyuma yo kuvanga kugirango ugereranye.

7. Ibikoresho byo gupima
Guhitamo ibikoresho byo gupima visosi ni ngombwa. Ibikoresho bisanzwe birimo amashusho ya vicome, Visiporo, na r hemeter. Buri gikoresho gifite amahame yacyo kandi gikwiriye bitewe nurugero rwa virusire nibintu byihariye bya Mristar bigeragezwa. Calibration no kubungabunga ibi bikoresho birakenewe kubipimo nyabyo.

Gupima virusi itera minisiteri yumye ikubiyemo HPMC ni inzira nyamwinshi yatewe nibintu bitandukanye birimo ibihimbano, uburyo bwo kuvanga, ibintu byamazi, nimyaka ya pertar. Porotokole isanzwe no gusuzuma neza ibyo bintu ni ngombwa kugirango ubone ibipimo byizewe kandi bihamye. Mu gukemura ibibazo no gushyira mu bikorwa ibikorwa byiza, ibipimo nyabyo byagaragaye neza birashobora kugerwaho, kwemeza imikorere yifuzwa ya minisiteri yumye mu miryango ivanze.
